Answer:

Step-by-step explanation:

$890 × 1.06 = $943.40

Answer:

False

Step-by-step explanation:

I will use an example here:

Original price of a pc is $799

you use your 20% off coupon which will bring it down:

799 decrease 20% =

799 × (1 - 20%) = 799 × (1 - 0.2) = 639.2

then you use your 10% off coupon:

639.2 decrease 10% =

639.2 × (1 - 10%) = 639.2 × (1 - 0.1) = 575.28

our final price doing them separately is $575.28

while doing it in one step by subtracting 30%:

799 decrease 30% =

799 × (1 - 30%) = 799 × (1 - 0.3) = 559.3

our price by doing it with a 30% discount is $559.30

Answer:

a1 =1

a2= 1/3

a3= 1/12

a4 = 1/60

Step-by-step explanation:

a(n+1) = an/(n+2)

if n=1

a(1+1)= a1/(1+2)

a2= a1/3

a2= 1/3

if n=2

a(2+1)= a2/(2+2)

a3= a2/4 = a2 × 1/4

a3= 1/3 × 1/4 = 1/12

if n=3

a(3+1)= a3/(3+2)

a4= a3/5 = a3 × 1/5

a4= 1/12 × 1/5 = 1/60

The value of [tex]\rm a_{1}, \rm a_{2}, \rm a_{3}, \rm a_{4}[/tex] for a given expression [tex]\rm a_{n+1} = {\frac {a_{n}} {n+2}[/tex] is 1, 1/3, 1/12, and 1/60.

We have given [tex]\rm a_{1} =1[/tex] and [tex]\rm a_{n+1} = {\frac {a_{n}} {n+2}[/tex] for n≥1 we need to determine the value of [tex]\rm a_{1}, \rm a_{2}, \rm a_{3}, \rm a_{4}[/tex] .

To solve for n terms, we will substitute the value of n = 1,2,3,4 and so on sequence-wise in the given expression.

if n = 1

[tex]\rm a_{1+1} = {\frac {a_{1}} {1+2}[/tex]

[tex]\rm a_{2} = {\frac {a_{1}} {3}}\\\rm a_{2} = {\frac{1} {3}[/tex]

if n = 2

[tex]\rm a_{2+1} = {\frac {a_{2}} {2+2}}\\\rm a_{3} = {\frac {1/3} {4}}\\\rm a_{3} = 1/12[/tex]

if n = 3

[tex]\rm a_{3+1} = {\frac {a_{3}} {3+2}}\\\rm a_{4} = {\frac {a_{3}} {5}}\\\rm a_{4} = 1/12 \times 1/5\\\rm a_{4} = 1/60[/tex]

So, the value of [tex]\rm a_{1}, \rm a_{2}, \rm a_{3}, \rm a_{4}[/tex] is 1, 1/3, 1/12, and 1/60.

Answer:

296

Step-by-step explanation:

8 plants × 37 on each = 296 cucumbers

Answer: 296

If you multiply the 37 green cucumbers each by the 8 cucumber plants they grew from, you'd end up with 296 green cucumbers altogether.

Answer:y = 10.5

Step-by-step explanation:

First, assign a variable to each unknown value.

Let:

x = cost of the pepperoni pizza

y = cost of the plain pizza

Next, set up equations based on the word problem. We then have the following equations:

(1) 3x + 2y = 58.50

(2) 2x + 4y = 67

Equation (1) comes from the statement: "Jack paid 58.50 for 3 pepperonies and 2 plain pizzas". Equation (2), on the other hand, translates the statement: "Jill paid 67 for 2 pepperonies and 4 plain pizzas".

To solve for two unknown variables given two independent equations, eliminate one variable first. That is, multiply equation (1) to -2.

-2[3x + 2y = 58.50]

-6x -4y = -117

Then add this to equation (2):

-6x -4y = -117

2x + 4y = 67

-------------------

-4x        = -50

x = -50/-4 = 12.5

To solve for y, we use equation (2) and substitute the value of x which has been solved already.

2(12.5) + 4y = 67

y = 10.5

To summarize, they paid $12.50 for the pepperoni pizza while they paid $10.50 for the plain pizza.

Answer:

Percent of people satisfied with the​ car  = 70%

Step-by-step explanation:

Given:

Total number of people survey = 1,400

Number of people satisfied with the​ car = 980

Find:

Percent of people satisfied with the​ car

Computation:

Percent of people satisfied with the​ car  = [Number of people satisfied with the​ car / Total number of people survey]100

Percent of people satisfied with the​ car  = [980 / 1400]100

Percent of people satisfied with the​ car  = 70%
